Red Skull error! Illogical, Impossible!
As you may have seen Red Skulls in-game appearance. Well he has the cosmic cube, which is an infinity stone. This can not possibly work in any way shape or form.
Why?
In MARVEL, Infinity stones from different realms cannot coincide in the same realm. It is not physically possible.
Why? Say you use the Death stone in MCOC. That is from the battlerealm. Then take the infinity stone that Red Skull technically has possession of. The Space stone from the ninth realm. Put those two in the same place and the bearer disintegrates. This happens to Thanos in the comics, now, either this area was not explored, or I just exploited future mcoc plans.
